Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993920, here are decompositions:

  • 7 + 993913 = 993920
  • 13 + 993907 = 993920
  • 79 + 993841 = 993920
  • 97 + 993823 = 993920
  • 127 + 993793 = 993920
  • 139 + 993781 = 993920
  • 157 + 993763 = 993920
  • 241 + 993679 = 993920

Showing the first eight; more decompositions exist.
